1. An active suspension comprising a plurality of actuators such that a corresponding one of said actuators is provided to each vehicle wheel so as to support a corresponding part of vehicle load according to a target load value determined therefor, a transverse acceleration detection means for detecting transverse acceleration of a vehicle body, a means for dividing said vehicle load to be imposed on each vehicle wheel based upon the transverse acceleration detected by said transverse acceleration detection means through adjustment of said target load values, and a control means for controlling each of said plurality of actuators in accordance with said target load value therefor, wherein said vehicle load dividing means is adapted to provide a greater share of the vehicle load due to the transverse acceleration to be born on a rear vehicle wheel as said target load value on a front vehicle wheel at the outside of the turn increases.
